COMPANION

ROTV

Compact and modular towed sensor platform for efficient subsea and water column observation

Build COMPANION with an expert

COMPANION is a remotely operated towing vehicle (ROTV). It is a hydrodynamically optimised, compact and truly portable sensor platform designed for surveying and observation missions. COMPANION is particularly well suited for deployment from small vessels as well as USVs. Thanks to its modular design, the towed vehicle’s payload capacity and range of functions can be quickly adapted to new challenges.

Customer:

Rough use takes its toll: offshore, it’s not a question of if something will break, but when. The problem arises when spare parts are not readily available. Fortunately, 80 % of MATE’s components can be printed within 24 hours and delivered to you in no time.

ALWAYS READY

Damage is inevitable, but downtime is not.

GROWS WITH YOU

Designed to handle change.

What you deploy today is just the beginning. Thanks to its modular architecture, you can adapt, extend, or reconfigure your system solution if your requirements change – there’s no need to replace it!

Customer Opinion on COMPANION ROTV

We are proud owners of a COMPANION. We chose it because existing ROCVs were often too large, costly, and limited in their applications. COMPANION fills a clear gap in the market by providing a flexible and efficient solution for hydrographic surveys and marine research. Thanks to its outstanding modularity, it can investigate both the seafloor and the water column, while significantly reducing time, manpower, and maintenance costs.
